MA + A = AM

0(1)+0 = 1(0)

Seems equal to me, but what do I know...

2*0 + 0 = 0*2

2 != 1

Title: Re: Math question
Post by: SilverZ06 on April 09, 2012, 07:26:30 PM

because iirc two letters/numbers next to each other such as XY or MA in this case, implies X times Y or M times A. Or 9A is 9 times A

Therefor 8*9=72 + 9 = 81 which does NOT equal 72

However math class was a long time ago so I could be completely wrong  :lol

and if A does in fact = 0 in this example, M can equal any number you want as RTH pointed out.

Because without brackets it doesn't comply with math nomenclature, hence the question isn't "math question" anylonger, but "trick question" and OP should have never titled the thread she did.

only through logic, find numbers that fit and

ma=a=am



but I think Silver and Bighorn actually are correct in what they are teaching me. I'm a reasonable problem solver but i certainly am not a good mathematician  :)

^^ this.

usually two adjacent variables means multiplication. However, in this question they are meant to represent the values of the one's and ten's places in a double digit number.

crappy football team that fumbles a lot

0,0 + 0 = 0,0  is the only way to not use a logic fallacy and is the only thing that models reality .

its equivocation to say  89 + 9 = 98 therefore M= 8 A = 9   It is no longer math once u ask what M = and A =

M represents 8 and A represents 9  they have no mathematical value NONE they only have symbolic value.

its equivocations from an actual numbers value to a symbolic value.

so it a symbolic sense 89 + 9 = 98 therefore M represents 8 and A represents 9 could be considered true but M and A separate have no math value.



thats were i am at right now I see one mathematical representation ,but am still looking at it.

the problem would have no answer if you assume that AM is the same as AxM. Since MA would be the same as AM, adding 1 to MA would make it impossible to equal AM.

It works just fine if A = 0 and M can be any number.

Nope. In neither case will that work...

2x0 + 1 = 0x2
0 + 1 = 0

20 + 1 = 02
21 = 2  nope again!

The thread was titled "Math question". As such, nobody should assume that there is a possible solution.

That said, in this case, there are no bad answers, it's the question which is wrong.

Post by: Ardy123 on April 10, 2012, 11:21:00 AM
IF we are to interpret MA as M*A as would be via standard math nomenclature, then this question is as stupid as saying

a(0) + 0 = 0 what is a? or a/0 = b what is a?

Joachim's post about asking why we were interpreting it as multiplication seems to imply that the original question that was copied was

1) Not math problem but a riddle
2) As a math problem where MA is interpreted as M * A, the initial problem violates the commutative property of multiplication, unless one of the variables is 0 (thus giving the other infinite possibilities). ie [MA + A = AM] =  [(M + 1)A = MA] thus A = 0. M(0) + 0 = 0(M)

Not even remotely equal.

As long as something is probable, however unlikely, you can assume it could happen. But you can't take for granted something will happen, no matter how probable it is, as long as there is a chance it may not.

Well not really, not without losing a lot of properties, and really being a poor definition of number in general.  Something like IEEE 754-2008 (http://en.wikipedia.org/wiki/IEEE_754-2008) has the property that 0 * Inf = NaN, but this is stretching the bounds of your question.  All the numbers we would ever use like the reals, integers, complex, rationals, etc, will follow the field axioms (http://mathworld.wolfram.com/FieldAxioms.html).  I get the feeling bighorn knows more about math than I do, so if I'm wrong on any of this I default to him...

So basically, no.

Also see Rings (http://en.wikipedia.org/wiki/Ring_(mathematics)#Formal_definition).
